Is this question only to United Statians, or everyone in the whole wide world?
My main stressors in high school were:
1. Whether I can get to university for IT/telecom studies after the high school. I didn't at first try (I got to "machinery" and "construction building" department which just didn't interest me in the slightest, even if I was sure I could make a career out of them). I studied there one year (I remember learning how to draw some machinery schemas or whatever, and how to use CAD, LOL) and next year went to the entry exams again to the same university, and this time got to the "computer studies" that I was really interested in.
2. Where to find some attractive female as a girlfriend, or at least to have sex with. Still being a virgin in high school felt so stressing, as if I was the main protagonist of some stupid high school comedy movie, doing nasty things to apple pies etc.
3. The incoming military service, but for me that wasn't until one year after high school, but it still stressed me a bit even in high school.
4. Obtaining a driver's license. My father kept bugging me I should go to a driving school ASAP, but in the end I waited until I was 19 years old (ie. after the high school). My buddies at high school went to driving school already during the last year of high school, I didn't.
When I got to the driving school, I got the angriest and the most asshattest teacher of the whole school. God damn that old guy had some serious anger management issues, making even me nervous occasionally.
Like one time he suddenly shouted at my ear, why am I driving "too slowly"? I was puzzled what the hell is he on about, and then he was like "Oh, I saw the speedometer wrong as I was looking at it from an angle, forget what I said...". Yeah, whatever, asshat.
5. Forgot one: during the second year of high school, at least there used to be a custom that the second year class students attend a ballroom dancing party ("Vanhojen tanssit", meaning "The old people's dance party" or something like that), kind of celebrating that they will become the "oldest" students in the school after the third-year high school students start concentrating on their final exams.
So a bit like those high school graduation parties ("senior prom"?) in American movies like Carrie, except that we don't vote for the King and Queen of the party, and throw pig blood on them, which seems to be customary in US. Instead we dance in lines old folk's dances that we have rehearsed beforehand together, all dressed up like some fjucking royals.
Anyway, when the dancing rehearsals at the school were starting, everyone was supposed to participate, and everyone was supposed to find a suitable dancing partner. And then the teachers would join the odd couples, the leftovers. Naturally all the cool guys got the prettiest girls etc., if was all very hetero-normative, you needed to be proactive if you wanted a certain dancing partner etc. Of course it would be quite embarrassing if you would be without a dancing partner of the opposite sex.
Anyway, I was just lazy, I wasn't interested in the slightest participating in those dancing rehearsals. I just felt they were boring and waste of my precious (gaming) time. I didn't even try to find a partner, and then the teacher told me there is an free female student who would like to have me as a dancing partner. She was from another class and I didn't know her well, she was kinda shy and silent and "odd", I don't think we had ever said a word to each other.
I didn't really have anything against her, I just didn't want to participate to the dancing rehearsals (I think they were arranged after school, ie. at my free time), or even the whole party, if I just could avoid it. So I didn't.
Anyway, the teacher sometimes asked me about it and made it clear that girl is quite devastated because I don't seem to be interested in being her dancing partner, and yeah that did make me feel bad. I wish I could have told her it is not her fault, but me. I just don't want to dance because cool guys don't dance.
Who knows, if I had accepted that dancing invitation, maybe I could have gotten rid of one of my other stressors (virginity) already then, and she would have become my first true girlfriend (not counting the girl next door with whom I spent a lot of time when I was like 5-10 years old)? I will never know. Fortunately, I did get rid of it a few years later though, after which I became a real man and obtained my superpowers.
Orkhepaj: stressors what is that?
I looked it up in Google Translate, just to make sure what it is (I guessed right).
You should too. Google is your friend, because only a true friend knows even your deepest secrets, like Google does.
